A light weight, portable aquatic vegetation cutter having a handle (404) disposed at one end of a mounting rod (408), a motor (418) at the other end of the mounting rod, the motor being disposed essentially centrally between two reciprocating type cutting blade (424) assemblies ranging in opposite directions from the motor, the handle being adapted substantially to indicate the horizontal disposition of the cutting blade assemblies and permitting their realignment relative to the direction in which aquatic vegetation cutting takes place, the position of the motor with the cutting blade assemblies being perpendicular to each other and being adjustable in two directions relative to the vertical, an optional boat mounting attachable from the mounting rod, providing three additional directions of yieldable freedom of motion, optional audible and visual means for signaling a problem in cutting ability of the aquatic vegetation cutter, an optional switch enabling momentary reversal of the polarity of DC current to the motor for freeing matter caught between the toothed reciprocating cutting blade and toothed stationary cutting blade of a cutting blade assembly, and an optional switch for preventing turning the motor on when it is not immersed into a sufficient depth of water. |
